Question

Trying to create a button_to that updates a single attribute, but I’m getting routing errors. Here’s the code:

<%= button_to 'update', :action => 'update', :controller => 'users', :form => {:user => current_user, :share_articles_on_facebook => true} %>

And the error:

No route matches {:action=>"update", :controller=>"users", :form=>{:user=>#<User id: 3, ema....

Adding an explicit :method didn’t fix the problem. Here are the routes:

    users GET    /users(.:format)    {:action=>"index", :controller=>"users"}
          POST   /users(.:format)        {:action=>"create", :controller=>"users"}
 new_user GET    /users/new(.:format)    {:action=>"new", :controller=>"users"}
edit_user GET    /users/:id/edit(.:format)      {:action=>"edit", :controller=>"users"}
     user GET    /users/:id(.:format)  {:action=>"show", :controller=>"users"}
          PUT    /users/:id(.:format)    {:action=>"update", :controller=>"users"}

So, simple mistake. It wanted an :id element, obviously.
